Adding 2nd keypad to M1

I've got one keypad and the ELK wireless receiver home run and it all works. I added a 2nd keypad and home run the power wires but ran the data a and data b back to the wireless receiver. Everything powers up but I can't get the 2nd keypad to enroll using the software and both keypads give me a buzzer sound when I try to use one. I have both keypads jumpered.

If I unplug one of the keypads (doesn't matter which one) everything works.

What should I check?

An option: Getting a databus hub might make things easier. It is cheap and takes out a lot of the complexity. I just bought a second one for my install.
It sounds like you are wiring this without one.

You should only have the jumper on the last keypad on the chain. Try removing one of the keypad jumpers.
